Any more XBOX exclusives?

I mean, it wasn't as much a "Super Smash Bros." type game as it was more like a traditional fighter, but it had some of their "Sony Exclusive" characters...
Though if I remember correctly, it boiled down more to "use final fantasy characters against eachother....scratch that, every battle is Cloud Strife vs Sephiroth"

I honestly can't remember the game title, though. Obviously, it wasn't that famous.

I think the only way a "franchise fighting game" would work on a Sony platform if it functioned more like traditional fighters, and they have Capcom help out with it (or at least heavily influence it). That's simply the only style I picture working with Sony characters. MmmmMMmm, Marvel vs Capcom-type game with assists of the likes of calling in Warhawks for air support.

Ratchet and Clank vs Sora would be ace!
I'm just wondering why they haven't done a game like this that's all
Here's some characters that I think would be included if there was such a game
Ratchet and Clank
Jak
Cloud
Brave (played on a demo)
Sora
Lara Croft
Daxter
Any other characters that were only exclusive to Sony?
